Energy Storage System

Energy Storage Systems are core technologies that contain and store energy. Specifically, we’re talking about an entire range of systems that we have developed for a wide range of applications. Always with the aim of storing energy, smoothing peaks and saving fuel. The best part is that the Energy Storage Systems can be adjusted according to the requirements of our customers quickly and down to the smallest detail.

For all those worrying about their energy costs, here comes the shocking news: there is a system that bypasses power peaks. Sounds likes magic, but it’s a highly intelligent technology. We have developed a system based on buffer batteries with suitable converters varying from 30 kW and several hundred kilowatts in size. Depending on the area of application, the operation may be fully automatic, or additional energy may be released based on start commands from machines and devices.

 

What suites best to store energy are so-called second life modules. For example, used batteries from electric cars usually have 80 percent of their original capacity left after 250,000 kilometers. They can be used in energy storage systems for decades, saving costs and resources for the complex manufacture of new batteries. The environmental balance of electric cars is improving significantly.

 

Cheaper, more environmentally friendly, low-maintenance and practically fail-safe! For Christopher Schöpf, founder and majority shareholder of e battery systems, these are the main advantages of the modular inverter.

 

The best part is that this solution can be installed in no time and works without an expensive upgrade to the mains connection and the associated costs. It can be combined with various solar installations and wind generators, as well as with fuel cells or for hydrogen production. Depending on the size, our staff can install an external powerhouse or single or small rows of cabinets.

30kW / 120kW systems

For applications that fall within this power range, a 19-inch cabinet with a 30 kW converter and 13 batteries (35 kW) can be used. Multiple converters can be connected in parallel, both to the mains and off-grid, so that systems can be configured with up to 120 kW.

Larger systems (>120kW)

These systems are configured by request and are often complete systems assembled in a container. The power consumption measurements are made via fast measuring devices that transmit the signal to start the system. This is because these often have a large capacity but small energy requirements.

Technology

To be able to measure a peak and be able to reach it, a particularly quick counter is integrated into the main connector. The converter then receives the command to supply additional energy. For applications where this is not possible, an additional counter is put in place. An additional start switch then starts the machine and directly controls the converter. Setting the correct parameters in the integrated control system prevents the main connection from being overloaded and peaks that incur additional costs occurring.

Examples

Energy consumption is relatively low in many production processes, but heavy loads must be shifted regularly. Trolleys and other lifting vehicles consume a lot of power and drive-up costs. Using the Peak Shaving System can reduce these costs.

 

If someone purchases additional forklift trucks for their warehouse, they will usually also need more energy for the main connection. If that isn’t possible for financial reasons, the Peak Shaving System can help. Forklift trucks with lithium batteries require a higher charging current. The economic alternative to this would be a battery buffer. But other machines also need a lot of energy, e.g. for molding plastic. The heating output is relatively consistent, but the press screw becomes a power guzzler when it starts up. You can bypass this peak within the available battery capacity.
